does head tracking work if you spin around in your chair?
ok stupid question but if your sitting in a rotating chair and wearing the rift if you spin around the chair (not really fast but like rotated slowly) would the head tracking move with you? or does it work more if you have to physically turn your head? just a thought!

It depends what the headtracking device is attached to.

Re: does head tracking work if you spin around in your chair
Because rift coaster isn't cool enough, we're going to spin you around in your chair as well.
Wherever the rift is pointed, regardless of if it's your head, hands, chair, or ceiling fan, it's going to track that movement.

Re: does head tracking work if you spin around in your chair
Yes it does. I use the rift in a 360 chair with sound feedback and all connections are wireless or come from the chair.
This enables 360 movement, so for example in HL2 you can turn the chair in the direction that you want to go and press forward. I find this way a much more realistic and comfortable feeling than physically facing in one direction IRL but moving/spinning in another direction IOR.
Hope this makes sense

It will work better than using your mouse to turn around, because there your body will move along with the VR scenery. No mouse-incuded vestibular mismatch nausea effects.

It will work best if your head is right above the seat post, which it will not be if you lean back in the chair.

Sounds cool man! Not quite sure how you are getting full 360 movement though. How do you prevent the Rifts wire's from tangling? Can you post a pic of your setup?kt9mango wrote:Yes it does. I use the rift in a 360 chair with sound feedback and all connections are wireless or come from the chair.

Oh man that would be cool if you could run the Rift Coaster while spinning around in a chair. Too bad you would strangle yourself in a mess of cords during the process.

Yes, of course it works if you spin around in your chair. It would even work in a revolving room or on a merry-go-round. It doesn't care what causes the rotation, it just measures the rotation.

FIRST i was going to think this Thread is more kind of Fun, BUT what is with:2EyeGuy wrote:Yes, of course it works if you spin around in your chair. It would even work in a revolving room or on a merry-go-round. It doesn't care what causes the rotation, it just measures the rotation.
a) the rotation of earth?
b) the rotation of Solar System?
c) the rotation of the milky way?
-> Headtracking is a function of the relative movement (x,y,z, omega - "or call it potato") to the absolute "start-Position"...
==> So, we have a Makro-Drift caused through a), b), c)

No, because the earths magnetic field don't care about the milky way, planets or other stuff (as far as i know) : p

If you think of yourself as the center of the universe, and the whole world revolves around you, there can be no vestibular mismatch!

Re: does head tracking work if you spin around in your chair
Because the Rift tracker samples at 1000Hz, the Nyquist theorem shows that as your chair rotation rate exceeds 500 rotations per second, temporal aliasing artifacts will make the world seem to be spinning backwards (i.e. the "wagon wheel effect").
My personal recommendation is to keep your chair rotation rate below 30,000 RPM to prevent such unwanted side-effects.
If you have not yet upgraded your Rift to the "thousands of frames per second" frame update rate that Michael Abrash says we need for convincing VR, then you may need to limit your chair rotation rate to an even slower speed. If your Rift can only do 60Hz frame updates, then I recommend that you keep your chair rotation rate below 1,800 RPM:

Re: does head tracking work if you spin around in your chair
indeed! please show - I like to turn in my chair, but do have the issue that after a full turn in one direction I need to turn "back" the other direction. A solution that would allow me to no longer have to watch out for the cable would be awesome. I guess I would kickstart such a chair (man I really want one now that you mentioned it).drgroove101 wrote:Sounds cool man! Not quite sure how you are getting full 360 movement though.

Re: does head tracking work if you spin around in your chair
I want a motorized chair that stays synchronized to in-game rotation (with foot rests):GeraldT wrote:...

That should really help to prevent motion sickness...
Maybe accelerator, clutch, and brake pedals on that foot rest too.
It looks like the "Exohaptic Easychair" design needs a rotation feature now too:

Too many projects, too little time...
To keep the cables from causing excess strangulation, you can use overhead (or in the chair base) slip-ring connectors like these:
http://www.mtbs3d.com/phpBB/viewtopic.p ... 98#p100598
But for higher quality video than a slip-ring connector may provide, you may want to use inexpensive wireless HDMI like this:

Without such cord-management solutions, there can be unwanted Rift cord-entanglement complications:

What about a zero gravity leaning chair?
